Verified step by step guidance1
Identify the mRNA sequence provided: 5′–AUG–UCU–UCG–UUA–UCC–UUG–3′.
Use the codon chart to translate each codon into its corresponding amino acid. Start with the first codon 'AUG', which codes for Methionine (Met).
Translate the second codon 'UCU' using the chart, which codes for Serine (Ser).
Translate the third codon 'UCG', which also codes for Serine (Ser).
Continue translating the remaining codons: 'UUA' codes for Leucine (Leu), 'UCC' codes for Serine (Ser), and 'UUG' codes for Leucine (Leu).
